Getting Rid CryptoWall 3.0
We reported yesterday that ransomware is back with CryptoWall 3.0. Now we know how to beat it.
If you've been infected with CryptoWall 3.0, you'll get the following message on your computer:
What happened to your files?
All of your files were protected by a strong encryption with RSA-2048 using CryptoWall 3.0.
More information about the encryption keys using RSA-2048 can be found here: http://en.wikipedia.org/wiki/RSA_(cryptosystem)
What does this mean?
This means that the structure and data within your files have been irrevocably changed, you will not be able to work with them, read them or see them, it is the same thing as losing them forever, but with our help, you can restore them.
How did this happen?
Especially for you, on our server was generated the secret key pair RSA-2048 – public and private.
All your files were encrypted with the public key, which has been transferred to your computer via the Internet.
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server.
What do I do?
Alas, if you do not take the necessary measures for the specified time then the conditions for obtaining the private key will be changed.
If you really value your data, then we suggest you do not waste valuable time searching for other solutions because they do not exist.
So, if you're seeing this, what do you do?
Step 1: If you don't already have anti-malware software, install one, run a full system scan and have it remove any malware it reports.
Step 2: Restore your encrypted files. Hopefully you're good about backing up your files (and if you weren't, maybe you will be now), so you can just restore your backup.
If you don't have backups, you can try using RectorDecryptor.exe and RakhniDecryptor.exe, which may or may not work. If that fails, try installing Shadow Explorer. Hopefully these will be able to reclaim the files that were encrypted and effectively lost by CryptoWall 3.0 without you having to pay the thieving hackers a dime.
